I have done it a few times, but only with ladies I had met a few times before and knew I connected with and had fun with. Otherwise it can be painful.
The type of session was more sensual/GFE and we would often lift together during the day and then have a full evening date. I have done this with both sessiongirls and with muscular escorts.
Nornally I invite them to join me on a business trip. Prices are fully negotiable as very few women do this often. If they have fun with you are you are taking them somewhere nice, it is a good value proposition for them.
I cant comment on who I took, but many are open to these options. YMMV.
